Generic Name: pramlintide (PRAM-lin-tide)
Brand Name: Symlin Pen
Symlin Pen is used along with insulin. It may increase the risk of severe low blood sugar caused by insulin. The risk may be higher in patients with type 1 diabetes. If this occurs, it is seen within 3 hours after an injection of Symlin Pen. Do not drive, or use heavy machinery, or do other tasks or actions that could be unsafe until you know the effects of this drug on your blood sugar. If very low blood sugar happens while you are doing any of these things, very bad injuries or death may happen. Discuss any questions or concerns with your health care provider.
Symlin Pen is used for:
Treating diabetes in certain patients who also use insulin.
Symlin Pen is an amylin analogue. It works by slowing down food digestion. This prevents blood sugar from rising as quickly after you eat. It may also help you feel full faster.
Do NOT use Symlin Pen if:
- you are allergic to any ingredient in Symlin Pen, including metacresol
- you have a condition that causes your stomach to empty very slowly (gastroparesis)
- you cannot tell when your blood sugar is low
- you take an alpha glucosidase inhibitor (eg, acarbose) or an anticholinergic (eg, scopolamine, hyoscyamine)
Contact your doctor or health care provider right away if any of these apply to you.

- Alpha glucosidase inhibitors (eg, acarbose) or anticholinergics (eg, scopolamine, hyoscyamine) because they may increase the risk of Symlin Pen's side effects
This may not be a complete list of all interactions that may occur. Ask your health care provider if Symlin Pen may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use Symlin Pen:
Use Symlin Pen as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Symlin Pen comes with an extra patient information sheet called a Medication Guide. It also comes with a "Patient Instructions for Use" sheet. Read these information sheets carefully before you use Symlin Pen. Read them again each time you get Symlin Pen refilled.
- Use Symlin Pen immediately before major meals, as directed by your health care provider.
- A health care provider will teach you how to use Symlin Pen. Be sure you understand how to use it. Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.
- Be sure you understand how to use the pen-injector. Be sure to check the dosing window before each injection to make sure you receive the correct amount of medicine. Ask your doctor or other health care provider any questions that you may have about Symlin Pen or about using the pen-injector.
- Do not use Symlin Pen if it contains particles, is cloudy or discolored, or if the container is cracked or damaged.
- Symlin Pen is given as an injection under the skin, usually in the stomach area or upper thigh. Do not inject Symlin Pen into the arm, because it may not absorb properly. Rotate injection sites so you do not use the same site repeatedly.
- Do not transfer medicine from the pen-injector into a syringe. This may cause you to receive too much medicine per dose and may increase your risk of serious side effects.
- Do not mix Symlin Pen with insulin or inject it in the same area as insulin. Inject Symlin Pen at least 2 inches away from where you inject your insulin.
- If you store Symlin Pen in the refrigerator, allow it to warm to room temperature before you inject a dose. This may decrease the chance of a reaction at the injection site.
- Symlin Pen may affect the way other medicines are absorbed into your body. Some medicines may need to be taken at least 1 hour before or 2 hours after using Symlin Pen. Talk with your doctor or pharmacist about how you should take any other medicines with Symlin Pen.
- Do not share pen or cartridge devices with another person even if the needle has been changed. Sharing these devices may pass infections from one person to another. This includes infections you may not know you have.
- Remove the needle after each injection. Store the pen without a needle on it.
- Keep this product, as well as syringes and needles, out of the reach of children and away from pets. Do not reuse or share needles, syringes, or other materials. Ask your health care provider how to dispose of these materials after use. Follow all local rules for disposal.
- Continue to use Symlin Pen even if you feel well. Do not miss any doses.
- If you miss a dose of Symlin Pen, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use Symlin Pen.
Important safety information:
- Dizziness may occur while you are using Symlin Pen. This effect may be worse if you take it with alcohol or certain medicines. Use Symlin Pen with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it. Talk with your doctor about the things you should avoid doing.
- Do not drink alcohol while you are using Symlin Pen. Drinking alcohol may increase the risk of developing low blood sugar.
- Nausea is a common side effect of Symlin Pen. Mild nausea is more likely during the first weeks of treatment and usually does not last long. Tell your doctor if nausea continues or is bothersome.
- Do NOT use Symlin Pen if your blood sugar is too low, you skip a meal, you plan to eat a meal with fewer than 250 calories or 30 grams of carbohydrates, you are sick and cannot eat your usual meal, you are pregnant or breast-feeding and have not talked to your doctor, or you are having surgery or a medical test in which you cannot eat.
- Do not use more than your prescribed dose of Symlin Pen without checking with your doctor. Using more than the prescribed dose may cause nausea and vomiting, and you may not be able to eat the amount of food you usually eat. If you use more of Symlin Pen than the prescribed dose, pay close attention to the amount of insulin use. You may have greater risk of developing low blood sugar. Contact your doctor or other health care provider for instructions.
- Tell your doctor or dentist that you take Symlin Pen before you receive any medical or dental care, emergency care, or surgery.
- Talk with your health care provider about all of your diabetes medicines and how to use them. Do not start, stop, or change the dose of any diabetes medicine unless your doctor tells you to.
- If you stop using Symlin Pen for any reason (eg, surgery, illness), contact your doctor. Follow your doctor's instructions for restarting Symlin Pen.
- Symlin Pen may increase the risk of severe low blood sugar caused by insulin. Low blood sugar may also occur if you use too much of Symlin Pen, use too much insulin, skip a meal, or exercise more than usual. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you more hungry. It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or non-diet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.
- Carry an ID card at all times that says you take Symlin Pen.
- Monitor your blood sugar levels as directed by your health care provider. Most patients will monitor blood sugar before meals, after meals, and at bedtime. If your blood sugar is often higher or lower than it should be, check with your doctor.
- Follow the diet and exercise program given to you by your health care provider.
- Ask your health care provider what you should do if you miss a dose of your insulin.
- It may be harder to control your blood sugar during times of stress such as fever, infection, injury, or surgery. If any of these occur, talk with your doctor. A change in your medicine may be needed.
- Lab tests, including fasting blood sugar levels and hemoglobin A1c, may be performed while you use Symlin Pen. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Symlin Pen is not approved for use in CHILDREN; talk with the doctor.
